4.21.5 Handling QoS Alarms
The application must first be enabled to receive notification of alarms on the specified line device.
The following code demonstrates how this is achieved.
/****************************************************************
* NAME: enable_alarm_notification(struct channel *pline)
* DESCRIPTION: Enables all alarms notification for pline
* Also fills in pline->mediah
* INPUT: pline - pointer to channel data structure
* RETURNS: None - exits if error
* CAUTIONS: Does no sanity checking as to whether or not the technology
* supports alarms - assumes caller has done that already
****************************************************************/
